My present improved apparatus is designed to meet several conditions aswill beexplained. As shown in Fig. 1,w-the range I0, Ashown in dot-and-#70 dash lines, vmay be a combination gas and oil -installation in whichseparate independently manufactured oil burners areinstalled and whichdonot come equipped with my apparatus. In another instance :the range Imay-be manufactured 5 together with `vanoil Lburnerhin which isincorporated my device or, an independently manufactured oilburner'using my improved apparatus may beinstalled in the olderconventional coal or combination ranges. Ineach instance ,theinstallation may differ slightly incorporating some or 5 all of thefeatures shown in the drawing, as will be described further along in thepresent specification.

In the assembled view shown at Fig. 1, it is to be assumed that theapparatus is to be added to conventional oil range burners incombination with `combination oil and gas ranges in which II illustratesa conventional perforatedsleeve together with the base I2 and supportI3. With such an installation, I mount my improved apl5 paratus I4 overthe sleeve II as a separate unit and support it in an adjustable manneron the inside surface of the range Iv, as shown in Fig. 1. The apparatusp roper comprises a top member I5, better shown in Figs. 1 to 4inclusive, which is further vprbvided with an opening I6 and a `depending flange Il, the `front side of which is open, as shown at I8 inthe bottom plan view illustrated at Fig. 3. On lthe top of the topmember I5 I have located boss members I9 and 2B which form open 25bearings in which is journalled a damper disc rnemberZI on trunnions 22and 23. On the outer endof the trunnion 22 I have provided a square end24 over which is fitted a hollow square tube 25. At Fig. 7 I have showna regulator member 30 comprising a shaft 26 squared at 2l and shoulderedat 2 8` and having an indicating handle member v29.- preferablypositioned so that its majoraxisles in the same plane as the diagonalcorners of the squared end 21. In Fig..4, it will be noted that'thesquared end of ,the trunnion 22 is located so that its diagonal cornersare at rightangles to the iiat sides of thedamper 2l such that theindicating handle member `29, when properly assembled, will properlyindicate .the position of 4U the damper from lthe koutside of the range,as shown in Fig. 1. Preferably the unit shown at Fig. r1 is cast inonepiece but it may be assembled from several pieces if desired. Whenthe member shown at Fig. 7 is assembledit is passed through 45 the irontof the range IILas shown at Figs. `1 and 2 and a compression spring-26is placed ontheinside. A retaining washer 211 -is then placedon theinner squared end 25 against the spring 261 and is held inlplace bymeans of a Cotter-pin 281 which passes through the pin hole 291 in themember 21. The squared member 25 4may be pinned at 30 to thetrunnion'memberM through the pinhole 3| or. it `may be `fixed to themember 2'I,k as the case may be.

It will thus be apparent that when the unit shown at Fig. 7 is pulledout from the outside of the range l it will be disengaged from thetrunnion 22 and the damper member 2| may then be readily lifted up andoff of the top I5. An eye member 32 is attached to the damper member 2|to facilitate its removal.

Attached to the under side of the top member I is a semi-circular sleevemember 33, the side facing the oven 34 of the range I0 being open. Thesleeve 33 is held in place in any suitable manner, as by the pin 35located in the bottom side of the top I5. This pin is located slightlyto the rear so that the sleeve 33 when in place is tightly bound againstthe recess 36 in'the back of the top member I 5. Any other suitablemeans of attaching the sleeve 33 to the top member I5, as screws orrivets, Will suffice equally as well.

The means for supporting the unit I4 in place is illustrated in Figs. 5and 6. In Fig. 6 I have shown bracket members 31 having open footportions through which bolts may pass to fasten the said brackets to thefront of the range I0, as shown at Fig. l. These brackets arereversible. On the top of these brackets I have positioned a horizontalslotted bar member 38 which may be bolted to the free legs of thebrackets 31. With such an arrangement it will readily be seen that I mayvary the elevation of the bar 38 together with the brackets 31 and vatthe same time I may vary the position of the bar 38 outwardly orinwardly with respect to the front of the range l0. At Fig. 5 I haveshown a perspective view of another bracket 39; the rear end of which isprovided with a right-angled wedge member 45|Y which is adapted to t inthe slot 42 in the bar 38. On the front end of the member 39 I haveprovided a vertical side member 43, the lower portion of which isslightly curved. The top p0rtion of the member 43 is adapted to beinserted in the recessed portion 36 of the top member I5 between thesleeve 33 and the back of the flange I'I, better shown at Figs. 3 and 4.The bottom portion of the member 43 bears against the lower portion ofthe sleeve 33 and supports it together with the top I5, as shown inFig. 1. In Vthe position shown in Fig. 1, the sleeve 33 is positionedclosely around the conventional perforated sleeve |I, the top edge ofwhich is slightly higher than the bottom edge of they sleeve 33.

It will thus be seen that in an installation of the type shown in Fig.1, my improvedapparatus may be positioned `and adjusted in any desiredrelation to the range burner within reasonable limits. In other words,it may be easily and quickly adjusted to its proper location with aminimum of effort andrtrouble.

In installations in which the oil burner is built into the range andproperly adjusted at the factory, the sleeve 33 and the conventionalsleeve |I may be made in onevpiece, as in Fig. 8. In'

such construction the upper portion 33a is open in the same manner asshown in Figs. 1 and 3 in the drawing, the open side being above theupper perforated portion of the sleeve IIa adjacent the oveny side ofthe range. With such construction the brackets and bar member shown inVFigs. 5 and 6 will be eliminated but the damper and apparatus shown inFigs. 2'and` 'l will be used.

In operation, the damper 2| performs a very essential and importantfunction. When the damper is positioned as shown at Figs. 1 "and 2 inthe drawingrthe maximum heat is Vdirected out over the top of the oven34 passing under'rthe open end I8 of the top member I5 in much the samemanner as disclosed in my previously referred to application. If it isdesired to divert heat from the oven to the top of the range the damper2| may be turned from the outside of the range and tilted to any angledesired thereby allowing the heat to be directly applied to the top ofthe range. The maximum position is naturally when the damper is in avertical direction. Inasrnuch as practically all range oil burners areinstalled in pairs it will be apparent that with my dampers 2| set atopposite angles I am able to concentrate or direct the heat 'in aconverging manner to the center of the top 0fV the range thereby greatlyintensifying the Y temperature at this point. At the same time, I

may divert only a portion of the heat generated sending some of it tothe oven and some to the top of therange, as desired. With such anarrangement the necessity of removing vthe covers shown in my priorapplication is avoided and much greater flexibility of heat control ishad making it possible to obtain concentrated heat on top of the rangeand at the same time getting suiiicient heat delivered to the oven forbaking.

Another important feature of the top member I5 which should not beoverlooked is the fact that the opening I6 in the top is smaller thanthe outer sleeve II and the result obtained is that the heat Visslightly retarded due to the fact that it is slightly converged towardthe center of the burner and thereby slowed Yup to the effect that thebase I2 becomes hotter and the gases are more completely burned greatlyincreasing the eiiiciency of the burner, the net-result of which is moreheat with less oil consumption than is possible where the sleeve I I Visnot in combination with the unit I4. -'Ihe heat trapped temporarilyunder the flanged top member I5 reiiects against the base or bowl of theburner causing more per- Vfect combustion of the gases generatedthereon.

.When the', above apparatus is used in certain types of older coalranges where the under side of the top of the range is lower it may bedesirable to remove the dampers from the` top I5 when all the heat isdesired to be directed or diverted under the top of the range owing tothe fact that insufficient clearance is present to allow the damper tobe'turned to a full open position, For such installations I haveprovided the eye member 32 so that a hook may be inserted therein andthe damper 2| removed entirely. When such removal is made it is onlynecessary to pull out the member illustrated at Fig. '7 and lift thedamper 2| off of the top I5 replacing it when it is desired to use theoven. Even under such installations the damper may be rotated part wayopen and when two units are opposed or converged toward each othersuflicient heat will be present on the top of the range for the greaterportion of the time. l

Itvwill thus `be seen that while I have shown my improved apparatussomewhat in detail yet it is to be understood that I may vary theconstruction in proportion within wide limits without departing from thespiritr of the invention.
